Reviewers find Nvidia's RTX Spark well ahead on local AI and behind the top chips on CPU

Windows Central and Tom's Guide each tested Nvidia's RTX Spark for a week in one laptop model, the Surface Laptop Ultra. Six partners start shipping this week, Windows Central says, so a pilot on any other chassis goes beyond what either review covered.

NVIDIA's RTX Spark laptops went on sale from ASUS, Dell, HP, Lenovo, Microsoft and MSI with up to 128GB of unified memory and 1 petaflop of FP4 compute. Both are peak ratings from NVIDIA's own release, so a team still has to benchmark its own models.

MediaTek will wire custom XPUs into NVIDIA's scale-up fabric as a prevalidated block

NVIDIA is licensing the Fusion chiplet, its C2C CPU attach and NVHBM to MediaTek and buying $3.5 billion of its convertible bonds, so the quickest route to a custom accelerator now ends inside an NVIDIA rack.
